I have just purchased WinWedge 32 Pro but I am unable to get data from my device. Basically I need to send a string to the device to get it to send data. The device is receiving the string but isn't sending anything back. I have used the device with HyperTeminal & this works as expected but not with WinWedge.

There are 3 possibilities, presented here in the order of most likely to least likely.

Usually when this happens it is because you are not sending a carriage return and or carriage return line feed at the end of the string from WinWedge. In the analyze window use the Ascii chart to add an Ascii 13 and an Ascii 10 to the end of the string and click on send. (If you press enter in HyperTerminal after entering the string then you must enter a carriage return at the end of the string in WinWedge.)

By Default, HyperTerminal uses "Hardware Flow Control", check the HyperTerminal settings and if this is the case then try using "Hardware Flow Control" in WinWedge.

Another possibility is that the device you are using cannot cope with the whole string arriving at once. In HyperTerminal most people assume that you must type "enter" at the end of the string to send it. In fact as soon as you push a key it is sent out the serial port. WinWedge does not send anything until you click on send at which point the whole string is sent. To test this type each character into the analyze window 1 character at a time, click send, delete it, then type the next character.
